My son is going to be getting a MTH B&O 0-4-0 Docksider (30-4026) set for Christmas (his first train!) that had belonged to his "Pops". I pulled it out to check make sure everything was working, and found the Work Caboose was missing the light bulb. After reviewing the MTH website it looks like this is an 18v bayonet base bulb. My question is could I get one of these from an online retailer or like the battery&bulb chain? It seems like most of what I found in my research was for automotive use or whatnot. I know MTH parts shipping is cost prohibitive for a $1 bulb.
As a side note, I'm super excited for him to get this set. I got my first Lionel train set when I was 6, which was also an 0-4-0 Santa Fe Docksider set. It just happened to work out that way, but really fun.
Thank you for any help you can provide
